Product Summary
The AD605BRZ is a low noise, accurate, dual-channel, linear-in-dB variable gain amplifier (VGA), optimized for any application requiring high performance, wide bandwidth variable gain control. Operating from a single 5 V supply, the AD605BRZ provides differential inputs and unipolar gain control for ease of use. Added flexibility is achieved with a user-determined gain range and an external reference input that provide user-determined gain scaling (dB/V). The applications of the AD605BRZ include Ultrasound and sonar time-gain controls, High performance AGC systems, Signal measurement.
